FEATURES OF RADIAL DENSITY DISTRIBUTION DURING RADIAL ISOSTATIC COMPACTION OF POWDERS

Abstract

The density distribution with the radius of porous permeable hollow cylinder produced by radial isostatic compacting is analyzed and calculated. The factors promoting a nonuniform density distribution in porous permeable materials during this type of compacting are determined by analytical calculations. It is proved that the optimal pore distribution across the section of a porous permeable material providing the maximum operating properties can be obtained by using the compacting procedure that allows relating the structural properties of the material with principal operating modes.
